Abstract
In this article, the recent development concerning the flame and fire-retardant characteristics of polymer-based composites has been discussed. The process of polymer combustion and its inhibition, and the chemistry behind the fire retardancy are mentioned in the background. Focussed are given on mainly inorganic hydroxide, halogen, phosphorus, nitrogen, silicon, boron, clay-layered silicates, metal hydroxides, and carbons based flame retardants as the use of these different nanofiller additives designed the polymer for enhancing flame retardancy. Emphases are given on how these nanofillers are beneficial to retard the flame from spreading during the development of fire. The usefulness to incorporate the conventional flame retardants in nanocomposites is also discussed. Finally, the mechanism of flame retardancy for clay-and carbon-based nanocomposites is reported.
